Major program to help improve sle quality especially among young adults; �151 diary markets targeted to receive cell-phone-only sling in Spring 2009 assuming completion of software to support rollout; � All markets except Puerto Rico to be cell-phone sled by Fall 2009 �Arbitron Inc . (NYSE: ARB) today announced that it plans to expand the introduction of cell-phone-only sling to 151 diary markets in Spring 2009 and to all markets (except Puerto Rico) by Fall 2009. This new implementation schedule significantly accelerates the company’s previously announced plan to introduce cell-phone-only sling to 50 diary markets in Spring 2009 and to a total of 125 diary markets in Fall 2009. “This is a substantial enhancement in sle quality and it demonstrates our ongoing commitment to improve the diary service. The Radio Advisory Council, the Diary Market Owner/Operator Caucus and the Media Rating Council all supported the introduction of cell-phone-only sling in diary markets,” said Pierre Bouvard, president, Sales and Marketing, Arbitron Inc. “Arbitron has been a recognized leader in cell phone only research and we’re pleased that for the second time in three short months, we are able to speed up our plans for getting these households into our diary sles.” Arbitron plans to use an address-based sle frame as the foundation of its cell-phone-only sle, while maintaining the rand om-digit-dial (RDD) sle frame for land line households. “The number of households that can be reached only by cell phone is growing rapidly and these households are more likely to include persons between the ages of 18 and 34.
By including cell-phone-only homes in the sle frame we will be better able to improve young adult proportionality in diary markets,” said Owen Charlebois, president, Technology and Research & Development, Arbitron Inc. The acceleration of cell phone-only sling to 151 markets in the spring assumes that the company is able to complete the development of software necessary to support the rollout as scheduled. If the company is not able to develop the software as expected, the planned acceleration of cell phone-only sling could be delayed.
Arbitron expects to confirm its plans for cell-phone-only sling for the Spring 2009 survey by late February. After all metro markets have cell phone sling, Arbitron expects to review options for expand ing cell-phone-only sling to the non-metro counties that are included in the RADAR, Nationwide and County Coverage reports. A list of the 151 markets scheduled for cell-phone-only sling in Spring 2009 is attached.
